Chiptuning, BMW Gxx 50d B57

My first impressions after the remap: the acceleration is much more dynamic, it feels like the car now has the powertrain that fits it well! I’m very satisfied with your service, explanations, and friendly approach. Thank you!

Mosselman tuned my BMW 318d today. What a result, it became a completely different car! Very professional company and friendly staff. This was my second car here and again they have exceeded my expectations. Thanks!

Very happy with my improved car, the car reacts better on the throttle and is very direct. Also, the exhaust sounds better!

With Mosselmans' performance package I exceeded even more than the company advertised on their website! The information-sharing process was easy and hassle-free. Excellent customer service from Leon and his team!

After 1,5 years still very happy with my iTronic. By far the best upgrade I could have done with my BMW 340i.
